Getting Started

Make sure to set the input option in Player Settings to new.

Keyboard

• Place the Keyboard prefab from Packages/Magic Leap XR Keyboard/Runtime/Prefabs/Keyboard Manager.prefab into the scene

Set Up Input Fields

• Add the script TMPInputFieldTextReceiver.cs onto any TextMeshPro Input Field you want to use with the Keyboard

Structure

The Keyboard prefab is structured in the following way:

• KeyboardManager.cs - Allows users to toggle the Keyboard on and off.
• Keyboard.cs - Manages multiple Keyboard Layouts and controls modifier key presses like Shift and Caps Lock
• KeyboardLayout.cs - groups the Keys and Keyboard Rows and communicates to the Keyboard Builder to generate a new layout if needed.
• KeyboardBuilder.cs - consumes JSON data to create the Keyboard Layout objects. The script requires that you assign the Keyboard Key and Keyboard Row prefab.
• KeyboardKey.cs - Controls the visual key graphics and input

Editing Layout

To edit the layout:

1. Create or navigate to an existing Keyboard Layout.
2. Edit the Keyboard Layout Data inside of the **Keyboard Builder ** component.
3. Press Regenerate Keyboard to update the keyboard layout in the scene.
4. When you are finished, modify the Layout ID and description.
5. Press Write New Json .to save the data to the Streaming Assets folder. Note: to toggle between Panels with a key press, assign the key's keycode as the Panel ID

Editing Visuals

1. Navigate to an existing Keyboard Layout.
2. Modify the Key prefab in the Keyboard Builder component.
3. Press Regenerate Keyboard to update the keyboard layout in the scene.

Unicode and Special Characters

Magic Leap XR Keyboard uses the following fonts to support unicode characters:

Label Name	Value
SHIFT_NEUTRAL	\ue5f2
SHIFT_SHIFT	\uf7ae

MRTK Integration

Hi, I was looking for a system keyboard for a MRTK 2.8 app and found this one, except it doesn't recognize MRTK Inputs. The hand ray goes through the object. I have tried implementing the IMixedRealityPointerHandler into KeyboardKey.cs, but it still doesn't work. Tried adding a nearinteractiontouchableUI on the key prefab as well.

Am I missing something ?

Thanks

Keyboard ignores custom content type keyboard type

If we set input type content type to custom and then manually select the keyboard type to e.g. Number Pad, TMPInputFieldTextReceiver component still spawns full keyboard (letters).

Expected behaviour is to behave the same way as the content type set to integer number or PIN.
